Sandia National Laboratories Intern - Nonlinear Mechanics and Dynamics (NOMAD) R&D Graduate Summer in Albuquerque, New Mexico
We are seeking an Intern Summer - R&D Grad
The Nonlinear Mechanics and Dynamics (NOMAD) Research Institute is a seven-week long program held at the University of New Mexico (UNM) that brings together researchers from around the world to work on challenging research problems in the engineering sciences. The Component Science and Mechanics Department is seeking motivated and productive student interns to contribute to a number of the summer research projects. The internship will provide the student with opportunities to work in diverse research teams, to participate in a research project that will be published as a conference paper, and to engage with professionals working within their research fields. The summer projects include:
- Constructing Optimal Surrogate Models for Bolted Fasteners in Multiaxial Loading. Utilize numerical studies to investigate the best strategies to simplify the geometry of threaded fasteners under multiaxial loading while also exploring the most practical and appropriate constitutive material model to reproduce multiaxial failure (computational).
- Influences of Modal Coupling on Experimentally Extracted Nonlinear Modal Models. Utilize a state of the art system identification technique to populate nonlinear modal models of an experimental system with jointed interfaces using both narrow and broadband excitation techniques, and validate their models using excitations over a broad range of amplitudes (experimental with computational).
- A Priori Methods to Assess the Strength of Nonlinearities for Design Applications. Explore a metric for design to quantify the strength of a nonlinearity in bolted structures using the magnitude and uniformity of the contact pressure within an interface and assessing the loads applied to the interface during modal excitation (experimental with computational).
- Fatigue Properties of Additively Manufactured Hiperco. Explore the effect of inherent flaws on the fatigue life of additively manufactured (AM) Hiperco material coupons in comparison to conventionally manufactured specimens and develop finite element models to predict crack growth as a correlation of the observed flaw size in AM materials (computational).
- Material Failure Model and Properties for Puncture Simulations. Utilize state-of-the-art material failure models to predict the kinetic energy required for a probe to penetrate a coupon of 7075-T651 aluminum and validate the predictions with existing experimental measurements (computational).
- Predictive Structural Dynamics Modeling of Bolted Interfaces. Explore the feasibility of developing a predictive structural dynamics finite element model of a bolted structure with preloaded interfaces by perturbing the discretized mesh to capture the curvatures on the interface observed with optical measurements and validating the predictions with experimental modal analysis (computational with experimental).

The Component Science and Mechanics Department conducts frontier mechanics research and science-based engineering solutions for component development and assessment. Focus areas for the department include interfacial and micro/nano-mechanics, probabilistic mechanics and uncertainty quantification, and mechanical aspects of component and subsystem reliability. Areas of active interest include: interconnects and encapsulation, fatigue and fracture, energy dissipation at contacts, micro-structural mechanics, shock and vibration, crack initiation and propagation, micro-scale diagnostics, and adaptive structures. Computational and physical simulations, including solid mechanics and structural dynamics for both linear and non-linear systems, are utilized in a dynamic multidisciplinary teaming environment.

This position does not currently require a Department of Energy (DOE)-granted security clearance.
Sandia will conduct a pre-employment drug testing, and a pre-employment background review that includes personal reference checks, law enforcement record checks, and employment and education verifications. Further, employees in New Mexico must pass a U.S. Air Force background screen for access to the work site. Substance abuse or illegal drug use, falsification of information, criminal activity, serious misconduct or other indicators of untrustworthiness can cause access to be denied or terminated, rendering the inability to perform the duties assigned and resulting in termination of employment.
If hired without a clearance, and one subsequently becomes required or you bid on positions that require a DOE-granted security clearance, a pre-processing background review that includes personal reference checks, law enforcement record and credit checks, and employment and education verifications may be conducted prior to a required federal background investigation. Applicants for DOE-granted security clearances must be U.S. citizens and be able to obtain and maintain the appropriate DOE security clearance as required for the position.
